Cyclodextrins (CDs), which also have the cylindrical structure, form inclusion complexes with various substrates and have fascinated many researchers as an enzyme model. We found the formation of inclusion complexes of some polymers with CDs and reported the supramolecular polymer complexes, such as rotaxanes and nano-tube etc. However, no rotaxanes, in which an axis molecule possesses the ability to grow up, have been reported. We found that CDs selectively include some lactones and initiate the polymerizations to give polyesters having a single CD molecule at the end of polyester only by mixing CD and lactones. Here, we have supposed that the polyesters having a CD would still have the polymerization ability for lactones. In this project, we show the construction of novel poly-pseudo-rotaxane with a growing polyester having a CD. Although an axis molecule itself did not show the polymerization activity for lactone, it has showed the activity by the formation of poly-pseudo-rotaxane. we report the oligomerization of lactone on the β-CD-based nano-sphere and show that an addition of α-CD to the nano-sphere led to form spherical supramolecule with poly-pseudo-rotaxane.

也具有圆柱结构的环糊精（CD）与各种底物形成包含复合物，并使许多研究人员作为酶模型着迷。我们发现某些聚合物与CD的纳入复合物的形成，并报告了超分子聚合物复合物，例如旋转烷和纳米管等。但是，已经报道了轴分子具有长大的能力的无旋转烷。我们发现，CD有选择地包括一些内酯，并启动聚合物，以使聚酯在聚酯末端仅通过混合CD和内酯在聚酯末端具有单个CD分子。在这里，我们认为具有CD的多植物仍然具有内酯的聚合能力。在这个项目中，我们显示了具有CD的生长的聚酯蛋白酶的新型聚二氧化杆菌的构建。尽管轴分子本身并未显示内酯的聚合活性，但它通过形成多峰核酸烷烷的活性。我们报告了内酯在基于β-CD的纳米球体上的寡聚化，并表明向纳米球中添加α-CD导致与多峰触发烷形成球形上分子。
